"Punched-in" values are not properly input. Possible latency issue.
For example, when punching in numbers to resize an object, the first number will often go ignored.
Also, when punching in new values for type (Font Size and Leading), when hitting TAB (from Font Size) to punch in a new Leading value, the value will not completely replace the current value if currently an "auto" value if I begin typing immediately. This results in an unwelcomed and unwarranted "invalid numeric value" popup.
This has been happening ever since I can remember (all CC versions)

This is seemingly more of an issue with CC 2021
